I chose just to use the filters. I'm not sure, number wise, what I gained but I do have better throttle response and seem to have picked up an mpg or 2 on gas mileage.

I was going to get the intakes but since they're located out in the engine compartment behind the radiator. I figure you're sucking in hot engine air and defeating the purpose of a cold air intake.

The original air intake is getting air through the grill. I figure it's colder air and just as good. Plus, you may or may not like the increased engine noise caused by the intakes.
